JENA-1198: Handling placement through property functions.
> Filter placement together with a property function can cause NPE.
> -----------------------------------------------------------------
>
> Key: JENA-1198
> URL: https://issues.apache.org/jira/browse/JENA-1198
> Project: Apache Jena
> Issue Type: Improvement
> Components: TDB
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
>
> TDB sets filter placement within BGPs to false (it does it itself).
> {{placePropertyFunctionProcedure}} does not handle the "no change" case
> properly. This arises when
> {{placeOrWrapBGP}} => {{wrapBGP}} which happens in the TDB case but not
> memory graphs.{{placeBGP}} happens to always rebuild, {{wrapBGP}} does not.
> {noformat}

> FILTER (!bound(?test))
